HDMI Tutorials and FAQ's


HDMI® cables have established a stronghold in homes and offices, but as far as wiring solutions go, they are still relatively young. Furthermore, the technology behind HDMI cables has been enhanced in a variety of ways. Check out our line of HDMI tutorials for more info.

Dealing with refresh rates and cable bandwidth can be tricky with HDMI because the cable isn't all that matters, the actual display also impacts performance. As such, let's look closely at what HDMI cables are able to accomplish in these areas and then talk about how those specs apply to actual usage when it comes to connecting to a display.

Convenience is central to the rise of HDMI cables across offices and living rooms alike, and audio return channel technology plays an integral role in taking this to another level. Very simply, audio return channel allows users to send audio from a television or similar device downstream to surround sound controllers or similar audio systems. Let's take a closer look.

On the surface, a conversation about backwards compatibility and cable lengths may seem like an unusual combination, but the reality is that you need to make sure any HDMI deployment is flexible, particularly if you are building the system in a commercial setting.

American Wire Gauge ratings are fairly straightforward, but understanding precisely how the AWG figure will impact performance can be difficult. Let's look at this issue piece by piece to unravel how wire gauge configurations impact HDMI performance.

The HDMI® cable features an internal wiring architecture that makes the solution applicable for a variety of purposes. With that in mind, we take a look at the various HDMI cable types that are available and in this tutorial discuss the different applications per type.  

HDMI cables offer numerous convenience advantages because they carry both audio and video signal at the same time, in high definition. The one problem with HDMI cables is that they are fairly thick and rigid. RedMere HDMI cables are a great thin solution for HDMI cabling.

HDMI cables feature a variety of connector formats that allow the wiring solutions to be used for everything from televisions and projectors to smartphones and tablets. With so many connectors available, let's take a look at each option and the various specifics of the different solutions.

The HDMI 1.4 standard is a more advanced form of HDMI cable that combines a variety of small upgrades to support new features and functionality. The physical difference between HDMI 1.4 or 1.4a and earlier standards aren't particularly important, but the various features that are enabled by the more sophisticated solution are extremely noteworthy.

Never overlook safety when making a cabling decision. The wrong cable in the wrong place can lead to significant safety hazards, as different coatings and materials used in the cable design dictate that solutions are used in specific ways. This tutorial goes over CL2 and CL3 HDMI cables.
